To allwiwm it may concern: 1

Be it known that I, Fmnorsoo CLARK, a citizen of Mexico and resident of Durango City, Durango, Mexico, have invented anew and Improved Combination Key Barrel Construction, of which the following is-a full, clear, and exact description. i 1

This invention relates to a combination key of the type having longitudinally adjustable ward members.

One of the objects of this invention is to provide a new and improved combination key so arranged and constructed that a pluprovide a combination keyhaving adjustrality of adjustable ward members may be provided in a minimum space, so that the ward membersm'ay be" conveniently and readily adjusted to various combinations, corresponding to the setting of tumbler members 'of a lock.

A further object. of this invention-is to provide a combination key of simple and compact construction having means so arranged and constructed that ward members may be conveniently and readily. adjusted longitudinally of the key body, without the necessity for the use of movable stops and spring members.

A further ob'ect of this invention is to able ward members'therein, so constructed and arranged that when the key is inserted within the key hole of a lock, the Ward members will actuate and position certain tumbler members of the look, while another portion of the key, preferably the key body, engages a bolt actuating element of the lock mechanism, so that relative rotary; motion may be effected between the wards and the key body or other part of the key engaging the bolt actuating element of the lock.

Still another object of this invention is to" provide a combination key of simple and compact construction, which is inexpensive to manufacture, and having the parts thereof so constructed'and arranged that the same may be readily assembled, adjusted or replaced. 1

' With these and other'ob' ects in view, the

invention consists in the construction and In: the practical embodiment shown, the

above objects are accomplished providing struction and arrangement being such as will perm1t relative rotary movement be tween the wards and the key body." The combination keymay be used for any 's'uitable, lock.

In the accompanyingfdrawings andde SCI1 pt1OI1, S1 II11ltLI' characters of, reference designate correspond ngparts 1n the several views.

With reference to the ,drawings representing a 'practical embodiment of the in-' vention, the key is shownas 7 comprising a handle 1 which may beof any suitable'form, and a core portion Q'preferably cylindrical, formingpart'of the key body Connected to the core, and extending from one end thereof, is agprojecting;portion3 shown square in form,- whichportion is adapted to engage a member 4' ofalock, which member may be. arranged to 'aotuate'a bolt or latch 5 thereof. Any suitable means maybe employed forestablishing such a conned tion. In the formshownythe member lis cylindrical in form, and apin-ion 6 is mount ed thereon and arranged to engage a toothed) rack portion 7, of the bolt5,'so that when the 'bolt. actuating member a is"tur ned' by thekey, thebolt 5"may lie-moved. Ward [members 8 adjustable longitudinally of the key body are arranged about, the sameso as 110 vto substantially embrace or inclose the key body, the construction being such as will permit relative rotary movement between the wards and the key body, when the latter is inserted in the key hole of, a lock. In the form shown, the wards whenin position upon the key body, are arranged in cylindrical form, and in order that the wards '8 may be longitudinally adjustable of the core 2, and havea relative rotary movement-with respect to saidcore, the core 2 is provided with aplurality of spaced grooves 9 which extend circumferentially around the said core, and the wards are provided with projecting lips:10 adapted to fit within the grooves 9. The wards 8 may be adjusted to an position.longitudinally of the key body y' moving each ward so that its projecting lip 10 will engage the proper groove. urther, the grooves being continuous, relative rotary movement may be eifected' between the wards 8 and the core 2; In the form shown, the "wards are provided with tapered sides 11 and12, the topfand bottom 13 and 14 respectively thereof forming cylindrical arcs, so that the said wards may be arranged about the core 2, but it is understood that the wards may beofany suitable form, the essential feature being that the said Wards are adjustable longitudinally,

and may receive rotary movement relative to the key body. In'order that the wards may be maintainedin proper relative ar justed position,a tubular casing 15 is pro vided to fit over the wards, and is provided with an inwardly extending lip or web 1301':- tion 16 which fits between adjacent wards, and prevents relative rotation between the casing-15 and the said wards, thus holding the said wards in proper relative position. Asa means of. holding the tubular casing 15 v in proper adjusted position, relative tothe key: body, and to permit relative rotary.

movement therebetween, an annular collar 17 is arranged upon the core 2,-and abuts against a shoulder 18, and is. connected with the casin 15 by a screw 19 or other suitable means. Preferably, the core ,is provided with another. groove 20 extending circumferentially therearound, so that the inner end 19' of, the screw 19 may extend therein, thus permitting the casing 15 to receive a rotary movement with the wards relative to the core, and to prevent relative longitudinal movement'of the casinggwith respect,

to the core after the wards have beenproperly adjusted.

In operation, to change the setting of the ward members, the. screws19 are removed,

to permit the removal of the casing 15 after which the adjustment or the setting, of the wards is made, and then the casing is reapplied and secured inits proper by the screws 19. r i

In Fig.1, a key iS ShOWIl' positioned in'a position keyhole, showing the manner in which the wards 8 move tumbler members 21 a dis tance corresponding to the setting of the key. Each of the tumblers 21 is provided with a plurality of-pins 22 adjustable thereon and so arranged that when the tumbler is moved a distance corresponding to the setting'of the wards, an open pathway will be afforded which will permit a toothed seg-. ment 23 arranged circumferentially "upon the bolt actuating member 4, to turniwhich will permit the bolt 5 to be actuated. The.

tumblers 21 are arranged about the member l, so as to permit relative rotary movev ment between the said tumblers and the member 4, when the said member is turned by the key. A tubular casing 24 embraces the tumbler members 21, and holds them in.

proper relative positioirthe said casingbe' ing provided with an; inwardly extending web portion which projects between adjacent tumblers to prevent relative rotation. between the saidcasing and'the tumblers.

Preferably, the forward edgeof the c'asing 15 of the key, is provided with a project ing portion 25 which engages a corresponding recess 26 of escutcheon 27 formingthe entrance to the key hole. j Thisserves as an indicating mark to facilitate the proper positioning of the key in the-key hole, so that it is assured that the wards of the key hav- 7 ing a certain setting, will engage the tumthereto. By the use, of'such an indicating means, the key may beprop'erly inserted in the key hole, in the dark.

:blers of the lock adjusted to correspond Each tumbler is pressed forward by a spring finger 2-8 having one end thereof suitably connected to plate 29 and the broken dotted line. Asuitablelhousing 33 may be providedto guide the bolt .5.

' lVhile onej practical embodiment of the invention has been shown, and described herein,it is to be understood that the present invention isinot to be: limited to the de tails of construction shown therein, but that various changes and modifications may be made thereof without departing from the spirit andyscope of the invention, as particulalrly pointed out in the appended claims.
